This invention relates to improvements in radio tables.

It is one of the objects of this invention to provide a radio table, inwhich a complete radio apparatus and speaker may be so concealed thatthe table will have the appearance of being an ordinary occasional tableand in which, in spite of the concealed position of the speaker, thesound vibrations will be permitted to come forth therefrom '111 such amanner as to give true tone value.

A further object of this invention is to provide a radio table in whichmeans is provided for deflecting the sound vibrations emitted from therear of the speaker so that said vibrations will not interfere with orneutralize: the vibrations coming from the front of the speaker toimpair the tone value.

A more specific object of this invention is to provide an improved radiotable in which the apparatus and speaker are mounted upon a novel typeof baflie board, the said baffle board having a fence surrounding aportion thereof, the said fence decreasing in height toward the sides todirect the sound vibrations emitted from the rear of the speaker towardopenings provided beneath the table top, on each side of said bafileboard.

A further object of this invention is to provide a radio table in whichresilient feet are provided on which the receiver is adapted to bemounted, the said resilient feet preventing vibrations from the speakerfrom impairing the operation of the receiver and vice versa, and saidfeet further being adapted to elevate the receiver so that a portion ofthe speaker may extend therebeneath, the latter feature permitting amore compact construction. 1 I

A further object of this invention is to provide a radiotable in whichan opening is provided between the table frame and the top to permitsound vibrations to emerge therefrom, and also to permit a completecirculation of air beneath the table to carry away heat generated by thereceiver.

A further ob ect of this invention is to provide a radio table which issimple in construction, attractive in appearance, and well adapted forthe purpose described.

. to carry away heat from thefreceiver.

With the above and other objects in view, the invention consists of theimproved radio table, and all its parts and combinations, as set forthin the claims, and all equivalents thereof. I

In the accompanying drawings, in whlch the same reference charactersdesignate the same parts in all of the views:

Fig. 1 is a perspective view of the 1mproved table, the front panelbelng swung downwardly to permit access to the operating knobs;

Fig. 2 is a top view of the table, wlth the greater part of the tabletop removed to show interior construction;

Fig. 3 is a vertical longitudinal sectional view taken on line'33 ofFig. 2;

Fig. 4 is a vertical transverse sectional view taken on line 44 of Fig.2, parts being broken away; and 70 Fig. 5 is an enlarged fragmentarydetall view showing the means for providing an opening between the tableframe and top.

Referring to the drawings, the numeral 8 designates a table top, 9 thebody or compartment portion which is formed in part of side panels 10,11 the suporting legs, and 12 the stretcher or lower brace member whichconmeets the lower portions of the legs together, The table may be ofany desired shape, and in the form shown, the legs extend upwardly tothe top and the side panels are interposed therebetween, and with theexception of the front panel 10, arerigidly connected to the le SerialNo. 382,751.

vided with one or more depending fast Ding" members 14 which are adaptedtofit'wlthin clip members 15 (see Fig. 5) when thezltop 96 is closed tohold the top slightly above the table frame. This provides a space 16through which sound vibrations may come forth, and through which air-maycirculate creases toward the sides as at 23 (see Figs.

3 and 4) The receiver 24 is adapted to be mounted on resilient legs 25,constructed preferably of rubber and carried by the baflle board. Spacerblocks 26, extending inwardly from the ends of the fence are adapted toengage the sides of the receiver to position the same. Other spacerblocks 27 are positioned adjacent an opening 28 for the loud speaker 29.When the receiver is in position on the supporting legs 25, its rearportion fits agalnst the spacer blocks 27 as shown by the dotted linesin Fig. 4, and. the set being elevated by the legs, overlaps the flangedportion of the speaker as at 30. This permits a very compactconstruction.

The front panel 10 is hinged to the front lower edge of the baflle board19 or to any other desirable portion of the frame, to permit it to swingdownwardly to open horizontal position as shown. A supporting arm 31engaging the panel and the body of the table supports said panel when inopen position. Behind the panel 10 is an inner panel 32 which is formedwith an opening 33 for exposing the controls and dial of the receiver.

It will be noted from Fig. 2 that large openings 34: are providedbetween the partitions 18 and the side panels 10. Smaller openings 35are provided on the outer side of the fence 21, and other openings 36are provided between the sides of the baflie board and the partitionsnear the front of the table.

. It is also to be noted that the loud speaker is so carried by thebafile board that the sound vibrations will be directed downwardly bythe speaker toward the floor from the proper height 'to assure true tonevalue. If the speaker were supported too close to thefloor, the tonewould be distorted, and if it were positioned too far away thebeneficial results caused by directing the vibrations toward the floorwould be lost. When the radio is being operated, the majority of soundvibrations are emitted from the front of the speaker and said vibrationsare directed downwardly through the opening 28. However, othervibrations come forth from the rear of the speaker, and' it is foundthat in ordinary radio cabinets said vibrations frequently meet thevibrations coming from the front and interfere with or neutralize thelatter, thereby impairing the tone quality. Inthis improved radio table,however, the vibrations emitted by the rear of the speaker are separatedby the bafile board '19 from the vibrations emitted by thefront of thespeaker. By employing the improved bafile board with the fence 21, thesound vibrations coming from the rear of the speaker are caused totravel over a comparatively long path before emerging, and thereforethey will not cause interference. The major ity of said sound vibrationswill travel over the low side portions 23 of the fence, through therecesses 18 of the partitions 17 and out through the large openings 34between the partitions and the side panels 10. Other of the soundvibrations emitted from the rear of th'e speaker will pass over the highportion of the fence 21 and out through the openings 35. Still othervibrations will travel out through the openings 36 and through theopening 16 between the top and the table frame. Thus all of thevibrations coming from the rear of the speaker will be forced to travelover a comparatively long path and as a result there will be no inter-,ference with the sound vibrations emitted by the front of the speakerand a tone of exceptional quality and volume will result.

It will readily be seen that the elevation of the receiver by theresilient legs 25, in addition to permitting the overlapping of the edgeof the speaker, prevents vibrations caused by the speaker from impairingthe operation of the set. It will further be seen that by'having the top8 spaced from the frame to provide the opening 16, a completecirculation of'air from the bottom to the top of the compartment 9 ispermitted, to carry away heat from the receiver tubes.
